Unusual large water tank, considerations

[Jones82]

Hi Guys

I'd like your thoughts on this.

Customer has a 3 bar whole house shower pump and also an aqua lisa digital shower. Upon replacing the pump I noticed the water tank is only 50 gallons. It really should be 80-100 gallons? Its a 3 story town house with basement and two bathrooms.

However the space the tank resides in, a loft bedroom only has a small cupboard measuring 1200x850x1100. (LxWxH)

I've found these tanks 500l and 400l, yes they are a little pricey compared to standard tanks but will fit and look sound.

My two concerns are;

Are these tanks suitable for cold water storage cisterns... I can't think of a reason why not

The potential weight, structural considerations of a 500 litre tank. I would build a low level sturdy stand from moisture resistant flooring but the stand would essentially be sitting on the bedroom (loft) floor.

The tank would be located against what is essentially the gable end, so on the end of the joists. Its also a party wall as mid terraced.

But thats alot of weight in a house over 100 years old

Thanks as always

They dont say they are for potable/wholesome water.

Asking the manufacturer now, thinking about it a little more and the next concern would be insulating the tank.

I could easily fit a ball valve, overflow and screened vent to comply with the regs

The suitability of the tank seems to be down to its composition?

Like I said this all came about from a replacement pump job. I suspect the pump failed or certainly shortened its life span by running dry.

Even if they say it is suitable I'm not sure about the 4-500 kg weight at the top of the house....

You would need a structural engineer. Would be good to get it over a load bearing wall.

Luckily this one went on a concrete pad outside

does it need to be WRAS approved just wondering as it may comeback on you especially if it leaks at some point.

As long as its 600mm away I won't argue

It's a bit like some of those social distancing photos, it's all in the angle

Wow, how many litres/gallons is that one Simon?
